Tech Spotlight: How Sniper 2 Is Taking Plug-And-Play EFI To The Next Level - 07/18/2023
When Holley Performance introduced the original Sniper EFI system back in 2015, it kicked off a revolution in fuel injection conversions. The goal was simple: Make EFI simple and affordable for folks who’re looking to make the jump without completely reinventing their vehicle’s setup.
“The new system benefits from everything we’ve learned with Sniper 1 as well as the feedback that customers have provided to us,” /.../ “The throttle body, linkage, and key elements of the circuitry have been redesigned from the ground up for Sniper 2, and it offers a host of new features and capabilities. The development of the new system also provided us with the opportunity to streamline the system component selection process to ensure that customers get something that meets the specific needs of their project – whether that’s a basic EFI conversion, or something more comprehensive.” - Read More
Adding Additional Inputs And Outputs Is Easy With Holley EFI's CAN Input/Output Module - 03/07/2023
For high performance machines in the 21st Century, it’s all about control. Horsepower has never been easier to make, but to apply that new-found power means exerting intelligent control over how that power is applied. Electronics have become the easiest way to capture the data, create, and maintain that control. - Read More
Tech: How To Go From Carburetor To Fuel Injection - 08/18/2022
While there is certainly still a welcome place for carburetors in racing and classic vehicle restorations, considering the numerous advantages offered by EFI it has found a welcome adoption by vintage vehicle owners who love driving their cars. While old-school, cool certainly has its own virtues, fuel injection can do things that a carburetor’s mechanical systems simply cannot. - Read More
Which Holley ECU Is The Best For You? - 05/18/2022
Hot rodders and gear heads are the true definition of control freaks. In the early years of performance and racing, the focus was entirely on making horsepower. But now making power is much easier. Now the goal is as much about controlling the engine both from how much fuel and spark each cylinder needs along with accurately monitoring every nuance. This can’t be done by analog means with manual gauges and maybe a movie camera like our grandfathers did it. That’s just too cumbersome. Today it takes computer power. - Read More

How To Update Your Outdated ECU To Modern EFI - 06/15/2021
There are probably thousands of small-block Chevys running wild on the streets right now with an antiquated factory TPI system ECU. We’re talking computers with removable chips! An equally large number of small- and big-block engines are likely limping around on outdated and inefficient aftermarket fuel injection systems just begging for a more efficient way to manage spark and fuel. - Read More

Going In-Depth With Holley's Terminator X Stealth 4500 EFI System - 03/16/2021
Hot on the heels of the Terminator X Stealth 4150 EFI system that debuted earlier this year, Holley has now added the Terminator X Stealth 4500 EFI system to the lineup. As the name implies, the new hardware is designed to work with 4500 flange intake manifolds, but this system is much more than just a carburetor replacement that’s designed to improve drivability and throttle response. - Read More
How Does A Dual Sync Distributor Work And When Do You Need One? - 04/19/2021
Conventional distributors use centrifugal weights and springs to affect the engine timing. Essentially the faster the distributor spins, the more the weights move away from the center of the distributor, and that alters the engine timing in turn.
Although that design worked well enough for decades of automotive applications, it’s not exactly cutting edge tech by today’s standards, and it isn’t particularly user-friendly when it comes to tuning. - Read More
How To Choose The Correct Fuel Injector For Your Engine. - 04/15/2021
When it comes to engine performance, the buck ultimately stops at fueling. After all, if you don’t have enough juice to go with that cool air and hot spark, you’re ultimately selling yourself short. Worse still, a fuel system that can’t keep up with the rest of your setup can ultimately lead to engine damage. And that’s why it’s important to make sure the fuel injectors you’re using are up to the task. - Read More
